Engine Heater Core Hose Leaky

Been noticing coolant disappearing and I tracked it down today. When I get on it my inlet heater core hose blows coolant out where it meets the heater core. I haven't readjusted it yet but I'm curious if this is a sign of a bad head gasket? My coolant is also a suspicious color, but I can't tell if it's rust or oil. My oil level hasn't dropped and my oil looks clean. I plan on compression testing and checking the coolant pressure Monday. Just wanted some opinions.

Yup I'm in the process of flushing it again, I already flushed it at the beginning of the month but it was so bad that now I have to again. But I think you're right, doesn't appear to be a gasket leak thankfully.
